Question

given the function $f(x) = x^2 + 7$, find the indicated values.
a) $f(7)$
b) $f(a)$

$a)$ $f(7) = \square$ (simplify your answer.)

Explanation:

Step1: Substitute \( x = 7 \) into \( f(x) \)

We have the function \( f(x)=x^{2}+7 \). To find \( f(7) \), we replace \( x \) with \( 7 \) in the function. So we get \( f(7)=7^{2}+7 \).

Step2: Calculate the value

First, calculate \( 7^{2}=49 \). Then add \( 7 \) to it: \( 49 + 7=56 \).

Answer:

56
